I have installed 5.3.7RC1, but am having a date error. Please see attached screen shot. I have adjusted php.ini to date.timezone = 'America/Chicago', that with or with out single or double quotes - restarted httpd - even restarted the server. Nothing seems to stick, and the error remains. It is impacting a script. Any ideas?

The path is right, and that's what it shows in info.php as well. I went ahead and changed all 4 of the files listed above just to not leave any stone unturned. Everything works pretty good (I no longer care about that other script), but I don't know have any idea where the configuration files are read, or how it has the information is does have, like memory limit - which is 128M, even though php.ini shows 64M. This is really weird and I have no ideas at all. It looks like I messed something up.

Thanks Jorge, I know it. The mystery is - php is not reading this php.ini file - which is located in /etc/php.ini
I do not know how this can be. For instance I have set in php.ini -- memory_limit = 64M

Yet phpinfo() shows memory limit set to 128M. That's where I had it set prior to this current install. Somehow, whatever was set before I installed this version is still set, and no changes I make on php.ini are ever reflected in phpinfo().

I did not uninstall my prior version of PHP prior to installing this 5.3.7RC1 version. I have no clue at all how this works, but I suspect it has to do with not uninstalling the previous version first. This is just a dev machine, so it's the perfect educational tool for me. All my programs do work fine, php run fine - I cannot adjust any settings however. The previous php.ini file is stuck someplace in the twilight zone I guess, and is still in command.
